ABSTRACT:
A color printer includes a plurality of platens arranged on paper feeding path to feed paper on which a plurality of printing areas are arranged in series, a plurality of print heads arranged on the feeding path to face the platens to print data on the same printing areas of the paper fed on the feeding path, a feeding roller for feeding, to the print heads, the paper along the feeding path, a front-edge sensing section disposed between the feeding roller and a print head nearest the feeding roller to detect that the paper has been positioned at a printing start position, and a plurality of head lift mechanisms for setting the print heads from the platens to a standby position apart from the platens before the paper is fed to the printing start position and to a contact position at which the print heads come in contact with the platens after the paper has been fed to the printing start position. Particularly, the color printer has an engine controller for sequentially driving the head lift mechanisms to set the print heads to the contact position when the front edge of the paper has reached positions slightly advanced over the print heads.
